[0039] In combination with Figures 1-6 As shown in the drawings, the embodiments of the present disclosure provide an air deflector driving mechanism and an air conditioner.

[0040] Traditional wall-mounted air conditioners usually use a single air outlet, and a single air deflector is arranged on the side of the air outlet to rotate the air. As people's needs for air conditioners become higher and higher, in order to avoid cold air directly blowing on the human body, technicians add a new air outlet on the original air outlet of the air conditioner, and realize various air outlet modes through the cooperation of double air outlets and double air deflectors, and improve user experience, but the structure is complex and the cost is high. Some air conditioners use two or three air deflectors on one side of the air outlet, and realize reversing rotation of air through the cooperation of the air deflectors, but the air conditioner with multiple air deflectors is prone to problems such as flash gap and noise.

[0041] The air deflector 6 driving mechanism provided by the embodiments of the present disclosure comprises a mounting base 12, a limiting rod 4, a connecting mechanism 5 and a driving assembly. The mounting base 12 is used to be connected with a mounting base and is provided with a track thereon; the limiting rod 4 is slidably arranged on the track of the mounting base 12; the connecting mechanism 5 comprises a first connecting piece 51 and a second connecting piece 52, the first connecting piece 51 and the second connecting piece 52 are drivingly connected to two ends of the limiting rod 4, and the first connecting piece 51 and the second connecting piece 52 are used to limit the assembly of the air deflector 6; the driving assembly is arranged on the mounting base 12, the driving assembly is drivingly connected with the limiting rod 4 and the air deflector 6, the driving assembly drives the limiting rod 4 to move along the track to adjust the positions of the first connecting piece 51 and the second connecting piece 52, and the driving assembly is also drivingly connected with the air deflector 6; wherein the limiting rod 4 moves along the track to enable the first connecting piece 51 to assemble the air deflector 6 and the second connecting piece 52 to disengage from the air deflector 6; or the second connecting piece 52 assembles the air deflector 6 and the first connecting piece 51 disengages from the air deflector 6; and after the second connecting piece 52 or the first connecting piece 51 disengages from the air deflector 6, the air deflector 6 is driven to rotate and open.

[0042] Specifically, when the air deflector 6 driving mechanism is installed on the air conditioner, the mounting base 12 is fixedly installed on the inner wall of the shell 1 of the air conditioner. The driving assembly, the limiting rod 4 and the connecting mechanism 5 are arranged in the mounting base 12. The driving assembly can drive the connecting rod to move, and then drive the first connecting piece 51 and the second connecting piece 52 to rotate through the connecting rod; at the same time, the driving assembly is drivingly connected with the air deflector 6, and the driving assembly can drive the air deflector 6 to rotate. When the driving assembly drives the limiting rod 4 to move, one of the first connecting piece 51 and the second connecting piece 52 connects the air deflector 6, and the other disengages from the air deflector 6. When the first connecting piece 51 connects the air deflector 6 and the second connecting piece 52 disengages from the air deflector 6, the driving assembly can drive the air deflector 6 to rotate upward and open to guide the air supply downward; when the second connecting piece 52 connects the air deflector 6 and the first connecting piece 51 disengages from the air deflector 6, the driving assembly can drive the air deflector 6 to rotate downward and open to guide the air supply upward. In this way, through the cooperation of the limiting rod 4 and the connecting mechanism 5, the reversing switching air supply of the single air deflector 6 can be realized, and the cost is low.

[0043] Optionally, the first connecting piece 51 comprises a first positioning end 511 and a first rotating end 512, the first positioning end 511 is rotatably arranged on the mounting base 12, the first rotating end 512 is in transmission connection with the limiting rod 4, the movement of the limiting rod 4 makes the first rotating end 512 rotate around the first positioning end 511, and then the first connecting piece 51 is assembled or separated from the deflector 6; and / or, the second connecting piece 52 comprises a second positioning end 521 and a second rotating end 522, the second positioning end 521 is rotatably arranged on the mounting base 12, the second rotating end 522 is in transmission connection with the limiting rod 4, the movement of the limiting rod 4 makes the second rotating end 522 rotate around the second positioning end 521, and then the second connecting piece 52 is assembled or separated from the deflector 6; the first positioning end 511 and the second positioning end 521 are respectively located on both sides of the length direction of the limiting rod 4, so that one of the first connecting piece 51 and the second connecting piece 52 is in the state of being separated from the deflector 6, and the other is in the state of being connected with the deflector 6.

[0044] Optionally, the first connecting piece 51 and the second connecting piece 52 each comprise a limiting hook, the limiting hook comprises a hook body and a hook head 513 for hooking the deflector 6, the hook head 513 is located at the lower end of the hook body; wherein the first positioning end 511 and the first rotating end 512 are located on the hook body of the first connecting piece 51, and the second positioning end 521 and the second rotating end 522 are located on the hook body of the second connecting piece 52.

[0045] Specifically, the limiting rod 4 is inclinedly arranged at a certain angle with the air outlet 11, the first positioning end 511 and the second positioning end 521 are located at two ends of the limiting rod 4, the first rotating end 512 is located at one side of the limiting rod 4 close to the air outlet 11, and the second rotating end 522 is located at the other side of the limiting rod 4 away from the air outlet 11. In this way, in the heating working condition, the connection position of the crank 2 and the connecting rod 3 is always located in the lower area away from the first connecting piece 51, when the limiting rod 4 moves obliquely upward, the hook head 513 of the second connecting piece 52 moves obliquely downward to be disconnected with the air deflector 6, the hook head 513 of the first connecting piece 51 moves upward and drives the air deflector 6 to rotate downward to blow air. When the limiting rod 4 moves obliquely downward, the hook head 513 of the first connecting piece 51 drives the air deflector 6 to move downward, the hook head 513 of the second connecting piece 52 moves upward to connect the air deflector 6, and the air outlet 11 is closed. In the cooling working condition, the connection position of the crank 2 and the connecting rod 3 is always located in the upper area away from the second connecting piece 52, when the limiting rod 4 moves obliquely downward, the hook head 513 of the first connecting piece 51 moves obliquely downward to be disconnected with the air deflector 6, the hook head 513 of the second connecting piece 52 moves upward and drives the air deflector 6 to rotate upward to blow air. When the limiting rod 4 moves obliquely upward, the hook head 513 of the second connecting piece 52 drives the air deflector 6 to move downward, the hook head 513 of the first connecting piece 51 moves upward to connect the air deflector 6, and the air outlet 11 is closed. The air conditioner of the application has simple structure, low cost, and can meet the air supply demand of different working conditions while ensuring the air volume.

[0046] Optionally, the mounting seat 12 is provided with a track for limiting the movement track of the limiting rod 4, the track is linear, and the limiting rod 4 moves linearly under the limitation of the track. Specifically, the track includes two linear sliding strips, and the sliding strips are fixed on the mounting seat 12. The limiting rod 4 linearly slides on the two sliding strips to drive the first connecting piece 51 and the second connecting piece 52 to rotate.

[0047] Optionally, when the limiting rod 4 moves in the first direction of the track, the second connecting piece 52 rotates counterclockwise to be disconnected with the air deflector 6, the first connecting piece 51 rotates clockwise, and the air deflector 6 rotates upward around the first connecting piece 51 to open; or, when the limiting rod 4 moves in the opposite direction of the first direction, the first connecting piece 51 rotates counterclockwise to be disconnected with the air deflector 6, the second connecting piece 52 rotates clockwise, and the air deflector 6 rotates downward around the second connecting piece 52 to open. Wherein, the first direction refers to the obliquely downward direction along the track relative to the air outlet, the forward rotation direction refers to the clockwise rotation direction, and the reverse rotation direction refers to the counterclockwise rotation direction.

[0048] Specifically, the air outlet mode of the air conditioner indoor unit includes an upward air outlet mode and a downward air outlet mode. In the upward air outlet mode, the crank 2 rotates reversely, drives the limiting rod 4 to slide obliquely downward along the track, and further drives the second connecting piece 52 to rotate to connect and assemble the air deflector 6, and meanwhile, the crank 2 drives the connecting rod 3 to drive the air deflector 6 to rotate downward to guide air upward. In the downward air outlet mode, the crank 2 rotates forwardly, drives the limiting rod 4 to slide obliquely upward along the track, and further drives the first connecting piece 51 to rotate to connect and assemble the air deflector 6, and meanwhile, the crank 2 drives the connecting rod 3 to drive the air deflector 6 to rotate upward to guide air downward. Compared with the one-way air supply air conditioner indoor unit, the existing air conditioner indoor unit with reversible air supply has a small air supply range and limitations in some areas when the air conditioner indoor unit with double air outlets is used, and the air supply volume is low under specific working conditions when the air conditioner indoor unit with single air outlet and double air deflectors 6 is used, which cannot meet the user's demand. The present application can meet the demand of wide air supply range and large air supply volume through one air deflector 6, and has simple structure, low cost, and is convenient for maintenance and repair.

The limiting rod 4 comprises a linear tooth part 41, and the arc-shaped tooth segment 21 can be engaged with the linear tooth part 41 for transmission. Optionally, the driving assembly further comprises a driving motor, and the driving motor is fixed on the mounting seat 12. The main shaft neck is fixedly connected with a driving output end of the driving motor through the mounting seat 12. The driving motor drives the crank 2 to rotate, so that the arc-shaped tooth segment 21 rotates, the linear tooth part 41 is engaged with the arc-shaped tooth segment 21 for transmission, and the limiting rod 4 is driven to slide linearly.

[0050] Optionally, the arc length of the arc-shaped tooth segment 21 is less than the linear length of the linear tooth part 41, and the preset moving distance of the limiting rod 4 is equal to one-half of the arc length of the arc-shaped tooth segment 21. Alternatively, the linear length of the linear tooth part 41 is less than the arc length of the arc-shaped tooth segment 21, and the preset moving distance of the limiting rod 4 is equal to one-half of the linear length of the linear tooth part 41.

[0051] Specifically, the arc length of the arc-shaped tooth segment 21 is less than the linear length of the linear tooth part 41, and the arc-shaped tooth segment 21 and the linear tooth part 41 are coaxial when the air deflector 6 on the air conditioner indoor unit is in the closed state. In this way, the limiting rod 4 and the crank 2 can be engaged for transmission, so that the limiting rod 4 is driven to move by the crank 2, and the first connecting piece 51 or the second connecting piece 52 is further driven to disengage from the air deflector by the limiting rod 4. Moreover, by setting the arc length of the arc-shaped tooth segment 21 to be less than the linear length of the linear tooth part 41, the limiting rod 4 and the crank 2 can be more smoothly transitioned between the engaged transmission state and the disengaged state, and the moving stability of the air deflector 6 is improved.

[0052] Similarly, the linear length of the linear tooth portion 41 is less than the arc length of the arc tooth segment 21, and the guide vane 6 on the air conditioner indoor unit is in a closed state, the symmetry axis of the arc tooth segment 21 coincides with the symmetry axis of the linear tooth portion 41.

[0053] Optionally, the drive assembly further comprises a connecting rod 3, the crank 2 body further comprises a connecting rod 3 journal, one end of the connecting rod 3 is rotatably connected to the connecting rod 3 journal, the other end of the connecting rod 3 is rotatably connected to the guide vane 6; wherein the crank 2 rotates to drive the connecting rod 3 to move, and in turn drive the guide vane 6 to rotate. The connecting rod 3, the crank 2, and the limit rod 4 are in a transmission connection relationship, and by driving the crank 2 to rotate through a drive motor, the limit rod 4 and the connecting rod 3 can be simultaneously moved, thereby realizing smooth movement of the guide vane 6 in switching and rotating air guiding.

[0054] Optionally, the guide vane 6 comprises a guide vane body 61, a first swing arm 62 and a second swing arm 63. The guide vane body 61 comprises a windward face; the first swing arm 62 is fixed on the windward face, the first swing arm 62 comprises a first connecting column 621, and the hook head 513 of the first connecting piece 51 is used to hook the first connecting column 621; the second swing arm 63 is fixed on the windward face, the second swing arm 63 comprises a second connecting column 631, and the hook head 513 of the second connecting piece 52 is used to hook the second connecting column 631; a fixed seat 64 is fixed on the windward face, and the fixed seat 64 is pivotally connected with the connecting rod 3.

[0055] It can be understood that the number of the first swing arm 62, the second swing arm 63 and the fixed seat 64 of the guide vane 6 is two, which are arranged at both ends of the windward face of the guide vane 6, not only reducing the wind resistance and ensuring the stability of the guide vane 6, but also improving the beauty during the rotation of the guide vane 6.

[0056] Optionally, the windward face is an arc face. When the air conditioner indoor unit operates in the upper air outlet mode, the guide vane 6 is located on the lower side of the air outlet 11, and the airflow of the air conditioner indoor unit is guided through the windward face of the lower guide vane 6 to flow upward. When the air conditioner indoor unit operates in the upper air outlet mode, the guide vane 6 is located on the upper side of the air outlet 11, and the airflow of the air conditioner indoor unit is guided through the windward face of the upper guide vane 6 to flow downward.

[0057] Optionally, there is a size relationship between the parts of the air deflector 6 driving mechanism as follows: α / 360*πmz≥d*L1 / L2, where α is the rotation angle of the index circle of the arc-shaped tooth segment 21, m is the module of the gear part, z is the number of teeth of the arc-shaped tooth segment 21, d is the diameter of the first connecting column 621 or the second connecting column 631, L1 is the distance between the second positioning end 521 and the second rotating end 522, and L2 is the distance between the second positioning end 521 and the hook head 513 of the second connecting part 52. In the connecting state of the air deflector 6 and the second connecting column 631, it is state A, and in the state that the air deflector 6 just separates from the second connecting column 631, it is state B. The rotation angle α of the index circle of the arc-shaped tooth segment 21 is equal to the rotation angle of the crank 2 in the process that the air deflector 6 rotates from state A to state B. In this way, not only can the air deflector 6 be separated from the first connecting column 621 or the second connecting column 631, but also the air switching time can be shortened and the air switching efficiency can be improved.

The first adjusting hole 42 and the second adjusting hole 43 are elliptical through holes, and the long axis of the elliptical through hole is perpendicular to the track. The first positioning end 511 of the first connecting part 51 and the second positioning end 521 of the second connecting part 52 are fixed on the mounting seat 12, the first connecting part 51 can rotate around the first positioning end 511, and the second connecting part 52 can rotate around the second positioning end 521. Because the first convex column 5121 of the first rotating end 512 penetrates the first adjusting hole 42 and the second convex column 5221 of the second rotating end 522 penetrates the second adjusting hole 43, in the process of linear sliding of the limiting rod 4, the position of the first convex column 5121 and the second convex column 5221 in the elliptical through hole can be adjusted through the long axis of the elliptical through hole in the direction perpendicular to the track, so that the first connecting part 51 and the second connecting part 52 can move more smoothly to connect or separate from the air deflector 6 in the process of reversing switching air supply.
